PIC24FJ16GA002-I/SS - 32MHz 16KB Flash Microcontroller | Microchip
The Microchip Technology PIC24FJ16GA002-I/SS is a 16-bit PIC24F microcontroller with a 32 MHz operating frequency, 16 KB of Flash program memory, 4096 bytes of RAM, and 21 general-purpose I/O pins. It is packaged in a 28-pin SSOP and is designed for compact embedded control, lighting, industrial, and low-power applications. The device uses the PIC24F eXtreme low-power architecture and provides up to 16 MIPS instruction performance at 3.3 V.
A microcontroller is a complete programmable control system integrated onto one semiconductor device. The PIC24F family combines a 16-bit RISC core, Flash memory, SRAM, timers, communication peripherals, and general-purpose I/O in a single package. This allows a design to replace several discrete logic and memory components while providing deterministic program execution, interrupt handling, and efficient peripheral integration. PIC24F devices are commonly used where compact embedded intelligence, low power consumption, and a broad peripheral set are required.
Key device attributes include 16 KB of Flash organized as 5.5K by 24 bits, 4096 bytes of SRAM, 21 I/O pins, a 32 MHz system clock, and 16 MIPS performance at 3.3 V. A 17-by-17 hardware multiplier supports efficient single-cycle multiplication operations, while basic Code Guard security provides a hardware mechanism for protecting program code. These characteristics make the PIC24FJ16GA002-I/SS suitable for control loops, lighting management, and compact sensor-driven products.
The PIC24F CPU architecture uses a Harvard-oriented design with separate program and data memory spaces. Flash memory permits in-circuit reprogramming and field firmware updates, and the SRAM area can hold working variables, stack data, and peripheral buffers. The MCU also integrates conventional embedded resources such as timers, serial interfaces, interrupt control, and port multiplexing, allowing firmware to coordinate multiple time-sensitive tasks without adding external logic.
Typical applications include smart LED lighting modules, occupancy and environmental controllers, compact motor-control helpers, programmable logic controllers, industrial sensor nodes, and low-power consumer products. Its 28-pin SSOP footprint is useful where a through-hole package is unnecessary and a surface-mount assembly can reduce board area. The industrial-temperature ordering code supports deployments across a broad range of commercial and industrial ambient conditions.
For new layouts, use the pin-description table and recommended decoupling arrangement in the Microchip datasheet. Confirm the exact oscillator configuration, I/O multiplexing, programming pins, and peripheral assignments before layout release because the 21 I/O pins are shared with internal functions. Verify the maximum peripheral and operating-frequency conditions against the intended supply voltage.
